Document Type and Number:

WIPO Patent Application WO/2023/191450

Kind Code:

A1

Abstract:

An amorphous or semi-crystalline polymer/aPHA composition (masterbatch) has a high load of aPHA (30 to 50 wt% based on the total amount of the composition). A method for production of the composition includes two or more split feedings of the aPHA in a blending or mixing or compounding operation. The method includes feeding about 1-15 weight percent (wt%) of the total aPHA in a primary feed hopper of a blending or mixing or compounding apparatus and about 30-49 weight percent downstream in the process.
